PNEUMATIC MATTRESS-STUFFING MACHINE.

SPECIFICATION forming part of Letters Patent No. 752,662, dated February 23, 1904.

Application led February 3, 1903.

To a/ZZ whom it may con/cern:

Be it known that we, Louis W. ELLMAN and States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Pneumatic Mattress-Stuiiing Machine, of which the following is a specification.

This invention relates to certain improvements in machinery for stuiiing mattresses, and particularly to that class of mechanisms employed for preparing or renovating the fibrous stufling material and forcing the same under pneumatic pressure into a mattress or pillow tick.

The principal object of the invention is to provide a machine by means of which' the entire operation of preparing and cleaning the librous material and placing the same in the ticks may be carried on continuously, provision being made for removing filled ticks from the discharge end of the machine and placing empty ticks thereunder.

A further object of the invention is to provide for the escape of dust and dirt from the stuffing material before the latter enters the ticking and to permit the discharge of the air at a point considerably in advance of the mouth of the tick.

A still further obiect of the invention is to provide an improved mechanism for supporting and handling the ticks at the discharge end of the machine in order to facilitate the removal of illed ticks and the adjustment of empty ticks to filling position Without stopping the operation of the machine for any considerable length of time.

A still further object of the invention is to provide improved tick-supporting devices for holding the mouth of the tick suspended and. automatically adjustable to accommodate ticks of different size.

A still further object of the invention is to provide devices which may be substituted for the regular tick-supports when it becomes necessary to iill small mattresses or pillows.

With these and other objects in view the inventionV consists in the novel construction and arrangement of parts hereinafter de- Serial No. M1,720. (No model.)

scribed, illustrated in the accompanying drawings, and particularly pointed out in the ap` sacrificing any'of the advantages of the inven-` tion. Y

l In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of a mattress-stuffing machine constructed in accord ance with the invention. view illustrating a portion of the elevated trackways for the support of the tick-holders. Fig. 3 is a view corresponding to a portion of the structure shown in Fig. 1, drawn to a somewhat larger scale. Fig. 4 is a longitudinal sectional elevation of the same on the line 4 4 of Fig. 3. Fig. 5 is a. sectional plan view of one of the tick-supports on the line 5 5 of Fig. 4..V Fig. ,6 is a side elevation of one of the tick-supports. Fig. 7 is aside elevation of an attachment which may be substituted for the ordinary tick-support when pillows or the like are to be lled. Fig. 8 is a transverse sectional elevation of the same on the line 8 8 of Fig. 7. Fig. 9 is a sectional plan view lof the same on the line 9 9 of Fig. 7

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The cotton or other fibrous material to form the stuiiing material is placed in a gin 10 and delivered by the revolving brush of thelatter to the lower end of an inclined conveyertube 11, preferably of a Width about equal to that of an ordinary mattress and provided at intervals with dust-receptacles 12, across which extend louver-strips 13. The dust-boxes are substantially triangular in form and provided with hinged doors 14., which may be opened from time to time to remove the accumulated material. The discharge end of the convey'ertube is bent downwardly and terminates in a delivery-spout of the construction best shown in Figs. 3 and 4 and comprising a substan- Fig. 2 is a plan tially rectangular box 15, preferably divided into two chambers by a partition 16 in order to divide the material when it becomes neces- I sary to simultaneously fill a plurality of small ticks, and to further aid in the even distribution of' material the discharge end of the tube is provided with a number of partitions 17. The opposite sides of the box are formed of sheet metal, and at its ends are open spaces covered by sheets 18, of wire-gauze or similar material, through which the air passes and allows the stuffing material to fall by gravity into the tick. At the opposite end of the box 15 are inclined chambers 19 in order to deflect the air-currents, these chambers serving also to receive the particles of dust and dirt carried out through the wire-gauze with the air.

At points immediately below and adjacent f to the discharge-spout are trackways 20, forming supports for the tick-carriers, and for convenience in handling the latter additional trackways 21 are provided adjacent to the spout and of sufficient length to support any desired number of carriers. The tracks 20 may be placed in communication with the tracks 21 by means of a turn-table 22, suspended by rods 23, the transverse bar 24.having a central pivot-bolt 25 by which it is connected to a fixed support, the construction being such as to permit the free turning of the table in order to receive carriers with empty ticks from one section of the track and to discharge the filled ticks on the opposite section of the track, so that the filled ticks may be conveyed away to a convenient point for the finishing operation.`

The tick-carriers are of the construction best shown in Figs. 3 and 4. The upper portion of each carrier is in the form of an oblong box 27, provided at its opposite sides with angle-bars 28, which may be formed of wood or metal and serve as supports for small rollers 29, the rollers resting on the trackways for convenience in moving the carriers from place to place. At the ends of the oblong frame are depending bars 30 of contracted width at their lower ends, and to the opposite edge of each of these bars is hinged a bar or strip 31, the corresponding bars or strips at opposite ends of the carrier being connected by longitudinal bars 32 and constituting a substantially rectangular frame of which the opposite side members may separate to a greater or less extent, and the side bars may become slightly bowed, as indicated in Fig. 5. In order to prevent the escape of any of the material from the sides or ends of the carriers, the sides are covered by sheets of cloth or f similar flexible material, as indicated at 33,

and at the ends are overlapping plates 34 and 35, the plates 34 being secured to the rigid side bars 30 and the plates 35 being carried by the pivoted bars 31, the overlapping sheets forming closed ends, while permitting free spreading movement of the carrier.

To the lower bars 32 are secured a plurality of outwardly and downwardly bowed fingers 37, additional fingers being placed at the ends holding the clamp-bars elevated while a new tick is being placed in position we employ suitable tension-springs 40, extending between the clamping-bars and the side members of the oblong frame 27.

Where two small ticks are to be lled -at the same time, the tick-carrier is of slightly-modified construction, a pair of division-plates 41 being placed midway between the ends of the carrier, as indicated by dotted lines in Fig. 3.

The machine may further be utilized for filling pillow-ticks and the like, and where these are of small size and easily handled it is desirable to employ an attachment of the character illustrated in Figs. 7, 8, and 9, the attachment being of such construction that it may be conveniently stored at any part of the track 21 when not in use and then run into position under the discharge-spout when pillows and' the like are to filled. The pillowfilling device comprises an upper substantially oblong frame 50, having angle-bars 51, provided with rollers 52, adapted to the tracks 2O and 21 and divided into two compartments by partitions 53, as indicated bydotted lines inFig. 7. Secured to the lower portion of this filling device are auxiliary tracks 54, the tracks being supported by hanger-bars 55,depending from a rectangular frame 56, arranged near the lower end of the frame. To the opposite ends of the fixed track members are secured hinged extension-tracks 54', having hinged supportinglegs 57 arranged at their outer ends in order to provide an elongated track for the reception of the pillow-tick carriers. rThe trackextensions are connected by flexible cords or chains 58 to the frame, the cords or chains being run over small sheaves 59, so that when not in use the track extensions may be drawn up to the position shown at the right of Fig. 7. 1n one wall of each of' the chambers or iiues through which the filling material passes are glass panels 60, through which the passage of the material Amay be observed, the panels being removable or hinged, as shown in Fig. 8, so that access maybe had to the interior of' the chambers in case of' choking.

rJhe pillow-carriers are in the form of tapering spouts 62, formed integral with a casing which is divided into compartments 64, 65,

and 66 and the whole structure being hung v on the tracks 54,` as shown in Fig. 8. The partitions vbetween the spouts 62 and the compartments 64, 65, and 66 are' provided with panels 67, formed ofwire-netting to permit the free escape of air and dust, and at'the'A lower end of each spout are small spring-clips 70 for holding the pillow-tick in place. They track, with its extensions, is preferably of suficient length to hold three or'more of the double carriers, sol that while one carrier is in position under the filling-spouts the pre" viously-filled ticks of another carrier may be removed and at the same time empty ticks may be placed on a third carrier. In practice, however, it is found more convenient to employ only two of the duplex carriers, these being alternately moved to position under the lling-spouts.

The device may be employed for lling ticks of any size with fibrous material of any character, and the gin illustrated in the drawings may be replaced by any desired form of renovating device, or a simple blower may be employed to force the material up through the conveyer-tube.
